Answer:

b. if it's on .edu.com sorry if it's wrong

Answer:

Step-by-step explanation:

The total interest paid on each loan is different by about $34.75.

To calculate the total value of the loan with different compounding frequencies, we can use the formula for compound interest:

\(A = P(1 + r/n)^{(nt)\)

Where:

A = Total value of the loan (including principal and interest)

P = Principal amount (initial loan)

r = Annual interest rate (as a decimal)

n = Number of times interest is compounded per year

t = Number of years

Part A: Semi-annually compounded interest,

Given:

Principal amount (P) = $20,000

Annual interest rate (r) = 3% = 0.03

Number of times compounded per year (n) = 2 (semi-annually)

Number of years (t) = 10

Using the formula, we can calculate the total value of the loan:

\(A = 20000(1 + 0.03/2)^{(2\times10)\)

\(A = 20000(1.015)^{20\)

A ≈ 20000(1.34812141)

A ≈ $26,962.43

Therefore, the total value of the loan with semi-annually compounded interest is approximately $26,962.43.

Part B: Monthly compounded interest

Given:

Principal amount (P) = $20,000

Annual interest rate (r) = 3% = 0.03

Number of times compounded per year (n) = 12 (monthly)

Number of years (t) = 10

Using the formula, we can calculate the total value of the loan:

\(A = 20000(1 + 0.03/12)^{(12\times10)\)

\(A = 20000(1.0025)^{120\)

A ≈ 20000(1.34985881)

A ≈ $26,997.18

Therefore, the total value of the loan with monthly compounded interest is approximately $26,997.18.

Part C: Difference in total interest accrued =

To find the difference in total interest accrued, we subtract the principal amount from the total value of the loan for each case:

For semi-annually compounded interest:

Total interest accrued = Total value of the loan - Principal amount

Total interest accrued = $26,962.43 - $20,000

Total interest accrued ≈ $6,962.43

For monthly compounded interest:

Total interest accrued = Total value of the loan - Principal amount

Total interest accrued = $26,997.18 - $20,000

Total interest accrued ≈ $6,997.18

The difference between the total interest accrued on each loan is approximately $34.75 ($6,997.18 - $6,962.43).

The loan with monthly compounded interest accrues slightly more interest over the 10-year period compared to the loan with semi-annually compounded interest.

The equations are

a) Julie can type 25 words in 1 minute and Debbie can type 20 words in 1 minute

b) Julie can type 1500 words in 1 hour and Debbie can type 1200 words in 1 hour

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the number of words typed by Julie be = J

Let the number of words typed by Debbie be = D

a)

Now ,

Julie can type 50 words in 2 minutes

So , the number of words Julie can type in 1 minute = 50 / 2

Number of words Julie can type in 1 minute = 25 words

And ,

Debbie can type 300 words in 15 minutes

So , the number of words Debbie can type in 1 minute = 300 / 15

Number of words Debbie can type in 1 minute = 20 words

b)

1 hour = 60 minutes

The number words Julie can type in 1 hour = Number of words Julie can type in 1 minute x 60

Substituting the values in the equation , we get

The number words Julie can type in 1 hour = 25 x 60

The number words Julie can type in 1 hour = 1500 words

And ,

The number words Debbie can type in 1 hour = Number of words Debbie can type in 1 minute x 60

Substituting the values in the equation , we get

The number words Debbie can type in 1 hour = 20 x 60

The number words Debbie can type in 1 hour = 1200 words

Hence , the number of words per hour for Julie and Debbie are 1500 and 1200 respectively

Answer:

Onyango is 48, his daughter is 16 and his son is 12

Step-by-step explanation:

Let's call Onyango's age x, therefore his daughter and son's ages are 1/3 x and 1/4 x respectively. We can write:

x + 8 = 12 + (1/3x + 8 + 1/4x + 8)

x + 8 = 7/12x + 28

5/12x = 20

x = 48 → 1/3x = 48 / 3 = 16, 1/4x = 48 / 4 = 12

The number of children are there in the given scenario are 400.

Given that, the ratio of children to adults on a school trip is initially 10:1.

Here, the given ratio can be written as 10x:1x

5 more children and 5 more adults join the trip so that the ratio is now 9:1

10x+5:1x+5

The new ratio is (10x+5)/(x+5) = 9/1

10x+5=9(x+5)

10x+5=9x+45

10x-9x=45-5

x=40

So, the number of children =10x=400

Therefore, the number of children are there in the given scenario are 400.

Step-by-step explanation:

IF  x-4   is a factor, then putting in x = + 4    will make the polynomial = 0

5 ( 4^3) - 20 (4^2) - 5(4)  + 20   =   0    Yes...it is a factor

\(x - 4 = 0 \\ x = 4 \\ \)

substitute value of x in the function to see if it equals to zero , if not it won't be a factor of the function

\(5 {x}^{3} - 20 {x}^{2} - 5x + 20 = 0 \\ 5(4) ^{3} - 20( {4})^{2} - 5(4) + 20 = 0 \\ 5(64) - 20(16) - 20 + 20 = 0 \\ 320 - 320 - 20 + 20 = 0 \\ 0 = 0\)

so (x-4) is a factor for the function

The 95% confidence interval estimate of the percentage of orders that are not accurate is approximately (17.37%, 27.83%)

Let's denote p as the proportion of orders that are not accurate.

The sample proportion of orders that are not accurate is given by:

p(bar) = 70 / (239 + 70)

= 70 / 309

≈ 0.226

The standard error of the proportion is calculated as:

SE = √[(p(bar)(1 - p(bar))) / n]

= √[(0.226(1 - 0.226)) / 309]

≈ √(0.1785 / 309)

≈ 0.0267

To find the margin of error, we need to multiply the standard error by the critical value corresponding to a 95% confidence level. For a 95% confidence level, the critical value is approximately 1.96.

Margin of error = 1.96 × SE

≈ 1.96 × 0.0267

≈ 0.0523

Now we can construct the confidence interval:

Lower limit = p(bar) - Margin of error

= 0.226 - 0.0523

≈ 0.1737

Upper limit = p(bar) + Margin of error

= 0.226 + 0.0523

≈ 0.2783

Therefore, the 95% confidence interval estimate of the percentage of orders that are not accurate is approximately (17.37%, 27.83%).

What is the domain and range?

The domain and range are fundamental concepts in mathematics that are used to describe the input and output values of a function or relation.

The domain of a function refers to the set of all possible input values, or x-values, for which the function is defined.

The range of a function refers to the set of all possible output values, or y-values.

To find the domain and range of functions and represent them in different formats.

To find the domain and range of a function:

The domain refers to the set of all possible input values (x-values) for the function.

The range refers to the set of all possible output values (y-values) for the function.

To dilate the figure by a factor of 2, I will multiply the x and y-value of each point by 2. I plotted all the new points to find the new triangle. To dilate the figure by a factor of 2, I will multiply the x-value of each point by 2.

The exact solution of this equation involves solving a quadratic equation, which may not result in a simple integer value for x.

To find the point (x, y) on the function f(x) = 6 - 7x that is closest to the point (-10, -4), we need to minimize the distance between the two points.

The distance between two points (x1, y1) and (x2, y2) is given by the formula:

d = sqrt((x2 - x1)^2 + (y2 - y1)^2)

In this case, we want to minimize the distance between the point (-10, -4) and any point on the function f(x) = 6 - 7x. So we can set up the distance equation:

d = sqrt((-10 - x)^2 + (-4 - (6 - 7x))^2)

To find the point (x, y) that minimizes the distance, we can find the value of x that minimizes the distance equation. Let's differentiate the distance equation with respect to x and set it equal to zero to find the critical point:

d' = 0

Differentiating and simplifying the equation, we get:

(-10 - x) + (-4 - (6 - 7x))(-7) = 0

Solving this equation will give us the value of x at the closest point. Plugging this x-value into the function f(x) = 6 - 7x will give us the corresponding y-value.
